摘　　要：通过沉淀法和水热法制备得到Ag2O-ZnO-RGO(Reduced Graphene Oxide,RGO)三元复合纳米材料,采用FTIR、UV-Vis、SEM和EDS等分析测试仪器对制备的样品进行分析表征,同时对比研究了Ag2O、ZnO、Ag2O-ZnO和Ag2O-ZnO-RGO在可见光下降解罗丹明B的催化活性。结果表明,Ag2O-ZnO-RGO可见光下降解罗丹明B的降解率达84%,分别是Ag2O、ZnO和Ag2O-ZnO的1.52、1.68和1.21倍。Ag2O-ZnO-RGO(Reduced Graphene Oxide,RGO) ternary composite nanomaterials were prepared by precipitation and hydrothermal method.The samples were analyzed and characterized by FTIR,UV-vis,SEM and EDS,and the catalytic activity of Ag2O,ZnO,Ag2O-ZnO and Ag2O-ZnO-RGO in the degradation of rhodamine B by visible light was studied.The results showed that the degradation rate of rhodamine B by Ag2O-ZnO-RGO was 84%,which was 1.52,1.68 and 1.21 times higher than that of Ag2O,ZnO and Ag2O-ZnO,respectively.
